  1. Recycling

  2. What is it? • a process to change materials (waste) into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to plastic production.[1][2]

  3. Common Consumables • Plastic • Aluminum • Paper • Glass

  4. Plastic – a History • 1839 – Charles Goodyear – Vulcanization • 1846 – Charles Schonbein – Celluloid • 1909 – Leo Baekeland – Bakelite & Phenolic resins • 1930’s – Wallace Carruthers - Nylon

  5. Plastics – a Chemistry

  6. Plastics – a Process • Thermosets - must be heated, but once cooled they are hard and do not return to their original form • Polyurethane = wood sealant • Polyester = fabric • Epoxy Resins = wood glues • Phenolic Resins = Bakelite • Thermoplastics – must be heated, and when reheated they can change shape and be molded • Polyethylene = LDPE or HDPE; bottles, gloves, garbage bag • Polypropylene = car trim and battery cases • Polyvinyl Chloride = pipes and plumbing

  7. Plastics – a Recycling Fact • polyethylene terephthalate • Can be made into • Furniture • Carpet • Tote Bags • New Containers

  8. Plastics – a Recycling Fact • high density polyethylene • Can be recycled into • Laundry detergent bottles • Pens • Recycling Containers! • Lumber, Fencing, Flooring

  9. Plastics – a Few Good Videos • Great Ideas for Your Project! • Have kids make ‘snowflake’ ornaments?

  10. Aluminum – a History • Ancient Times – Greeks/Romans used the salts • 1825 – Han Christian Orsted – production • 1855 – Napoleon gave aluminum as gifts, most expensive metal in the world to create! • 1888 – Hall-Heroult Process made it cheap

  11. Aluminum – a Chemistry

  12. Aluminum – a Recycling Fact • All materials made from the same base! • It save 95% in energy to recycle aluminum and 95% in air pollution! • 60 day turn-around time (can-to-can) • Two-thirds of the aluminum ever produced is still in use today • Aluminum is recycled into • Cans • Cars • Housing

  13. Aluminum – a Few Good Ideas

  14. Paper – a History • 105 AD – first modern paper from recycled materials • 750 AD – Islamic world creates paper mills • 1843 – Canadian invents a way to make paper from wood pulp • 1896 – family in NYC begins recycling paper • 1993 – first year that more paper is recycled than put in landfills

  15. Paper – recycling facts • Paper production accounts for 35% of felled trees • 90% of paper pulp is from wood • 35%, by weight, of solid municipal waste is of paper origin • Average use of paper, per person globally, is 110 pounds a year • Recycling 1ton newspaper saves 1 ton of trees • Recycling other paper saves 2 tons of trees • The average web user prints 28 pages a day

  16. Paper – some crafts

  17. Glass – a history • 3500 BC – glass in Northern Syria, beads, accidents • 1300’s – Venice, Italy – ground quartz and added soda ash • England made many advances to glass

  18. Glass - Recycling • Should sort by color • Ground into powder • Reusable infinitely! • Glass can also be used in • Concrete • Brick Manufacture • Water filtrate • Abrasive • Oregon was first to pass “Deposit” laws

  19. Glass – some crafts

  20. More Glass Crafts
